Both fluoride and lead can cross the blood-brain barrier and produce toxic effects on the central neural system, resulting in low learning and memory abilities, especially in children. In order to identify the proteomic pattern in the cortex of young animals, from the beginning of fertilization to the age of postnatal day 56, pregnant female mice and pups(More)
Axonal and dendrictic degenerations were observed in non-skeleton fluorosis as the neurological manifestations. Microtubules, composed of the assembled tubulin dimers, are the essential cytoskeleton of axon and dendron. However, the effect of fluoride (F) on microtubules status and tubulin dimer expression in central nerves system remains largely unknown.(More)
Sperm hyperactivation is crucial for a successful fertilization; however, the influence of fluoride (F) to hyperactivation is still in its infancy. The purpose of this study was to investigate the effect of sodium fluoride (NaF) on sperm hyperactivation, Ca2+/CALM-CAMK2 signaling, and CatSper1 and CatSper2 mRNA expression in mice sperm. Adult male Kunming(More)
Exposure to fluoride can induce low sperm quality; however, little is known about the molecular mechanisms by which fluoride exerts its toxic effects. This study was conducted to evaluate ultrastructure, oxidative stress, and apoptosis in sperm of mice treated with 150 mg/l NaF for 49 days. Furthermore, microarray analysis was also utilized to characterize(More)
Sperm quality, sperm hyperactivation, and the gene expression of Catsper1 were studied in adult male Kunming mice exposed to 150 mg NaF/L for 7 weeks in their drinking water. Compared with the controls, sperm quality and the proportion of hyperactivated sperm were significantly decreased in mice treated with F. Likewise, the Catsper1 gene expression level(More)
Fluoride-induced low sperm motility was observed in accumulated investigations. However, the effect of fluoride exposure on ATP generation which is essential to sperm motility remains to be elucidated. In this study, 120 healthy male mice were orally administrated with 0, 25, 50, and 100 mg L(-1) NaF for 90 d. Results showed that compared with controls,(More)
Reproductive process covers lots of procedures, including capacitation, hyperactivation, chemotaxis and the acrosome reaction. Each plays an important role in the success of fertilization. Although multiple studies have reported the toxic effects of fluoride on the male reproduction, the effect of fluoride on sperm chemotaxis is little known. This study is(More)
Epidemiological and experimental studies have demonstrated the atherogenic effects of environmental toxicant arsenic and fluoride. Inflammatory mechanism plays an important role in the pathogenesis of atherosclerosis. The aim of the present study is to determine the effect of chronic exposure to arsenic and fluoride alone or combined on inflammatory(More)
Fluoride (F) and lead (Pb) are two common environmental pollutants which are linked to the lowered intelligence, especially for children. Glutamate, a major excitatory neurotransmitter in the central nervous system, plays an important role in the process of learning and memory. However, the impact of F and Pb alone or in combination on glutamate metabolism(More)
